Re: "gnus-picon survey: Please reply if you are using it"

I have it enabled too. The reason is most likely that it came out of

The documentation linked in one of the docstrings `gnus-picon-databases'
isn't even online anymore.

The last backup I could find is this one:

Question is does keeping it hurt?

Some might use it but don't read this list.
